Pin Description
Table 5.
1. None of the I/Os are True Open Drain: when configured as Open Drain, there is always a protection diode between the I/O
2. In the 100-pin package, this Alternate Function is duplicated on two ports. You can configure one port to use this AF, the
3. It is mandatory that the NJTRST pin is reset to ground during the power-up phase. It is recommended to connect this pin to
4. After reset, these pins are enabled as JTAG alternate function see
5. There are two different TQFP and BGA 64-pin packages: in the first one, pins 41 and 42 are mapped to USB DN/DP while
6. For details on remapping these alternate functions, refer to the GPIO_REMAP0R register description.

other port is then free for general purpose I/O (GPIO), external interrupt/wake-up lines, or analog input (ADC_IN) where
these functions are listed in the table.
NRSTOUT pin (if available) or NRSTIN.
general purpose I/O (GPIO), the DBGOFF control bit in the GPIO_REMAP0R register must be set by software (in this case,
debugging these I/Os via JTAG is not possible).
for the second one, they are mapped to P0.15/CAN_TX and P0.14/RX.
